Dominoes zero loss

  1. Jun 9, 2010 #1
    I was watching a video on youtube and thought about how well dominoes transport energy from one place to another. As soon as you set off one, it seems like you should be able to knock over an infinite amount of dominoes, but could you really? How would you prove if the initial energy you put in is ever lost?

    What about the potential energy stored in each one?

    The initial energy is just an activation energy and the situation is no different from how things burn: a small activation energy releases a large amount of stored energy and some of that released energy goes toward continuing the reaction.
